Me too. I'm using a MacBookPro with a GeForce 8600M GT (which,
according to the NVIDIA site, supports OpenCL but not CUDA).
OpenCLLink seems to install succesfully, and the low-level doc
examples seem to work ok. It gags, though, on the higher-level
functions, all with with the 'block size' message.
The 8600M doesn't do doubles, only floats, so my current suspicion is
that the high-level functions may be defined with features available
only on the high-level chip sets.
